A machine-tool safety device for a machine tool having a transmitting unit for transmitting an outgoing signal and a receiving unit for receiving an incoming signal. The machine-tool safety device has an adjusting unit for at least semi-automatically adjusting the outgoing signal to be transmitted.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A machine-tool safety device for a machine tool, comprising: a transmitting unit to transmit an outgoing signal; a receiving unit to receive an incoming signal; and an adjusting unit to at least semi-automatically adjust the outgoing signal to be transmitted; wherein the adjusting unit is at least partially composed of a feedback control unit which is provided for feedback-controlling a power of the outgoing signal to be transmitted, as a function of at least one signal parameter of the received incoming signal; wherein the feedback control unit is provided for determining a material parameter using the signal parameter.
2. The machine-tool safety device of claim 1 , wherein the material parameter is composed of at least one of a conductivity parameter, a thickness parameter, and a dielectric parameter.
3. The machine-tool safety device of claim 1 , wherein the feedback control unit is provided for determining the material parameter using a model calculation.
4. The machine-tool safety device of claim 1 , wherein the feedback control unit is provided for adapting the power of the outgoing signal to be transmitted to a dynamic range of the receiving unit.
5. The machine-tool safety device of claim 1 , wherein the adjusting unit has an evaluation unit for analyzing a subrange of a dynamic range of the receiving unit within which the incoming signal resides.
6. A saw machine tool, comprising: a machine-tool safety device, including: a transmitting unit to transmit an outgoing signal; a receiving unit to receive an incoming signal; and an adjusting unit to at least semi-automatically adjust the outgoing signal to be transmitted; wherein the adjusting unit is at least partially composed of a feedback control unit which is provided for feedback-controlling a power of the outgoing signal to be transmitted, as a function of at least one signal parameter of the received incoming signal; wherein the feedback control unit is provided for determining a material parameter using the signal parameter.
7. A method for a machine-tool safety device, the method comprising: at least semi-automatically adjusting, using an adjusting unit, an outgoing signal to be transmitted; wherein the machine-tool safety device includes: a transmitting unit to transmit an outgoing signal; a receiving unit to receive an incoming signal; and the adjusting unit to at least semi-automatically adjust the outgoing signal to be transmitted; wherein the adjusting unit is at least partially composed of a feedback control unit which is provided for feedback-controlling a power of the outgoing signal to be transmitted, as a function of at least one signal parameter of the received incoming signal; wherein the feedback control unit is provided for determining a material parameter using the signal parameter.
8. The method of claim 7 , wherein a power of the outgoing signal to be transmitted is at least semi-automatically adjusted.
9. The method of claim 8 , wherein the power of the outgoing signal to be transmitted is at least semi-automatically feedback-controlled.
10. The method of claim 8 , wherein the power of the outgoing signal to be transmitted is feedback-controlled as a function of at least one material parameter of a workpiece to be machined.
11. The method of claim 8 , wherein the power of the outgoing signal to be transmitted is adapted to a dynamic range of a receiving unit.
